Excimer laser phototherapeutic keratectomy (PTK) effectively treats corneal surface diseases, including recurrent erosions and persistent epithelial defects. This therapy offers significant visual improvement and relief for conditions like bullous keratopathy.

Area of Science:

  • Ophthalmology
  • Laser Surgery

Context:

  • The excimer laser is increasingly utilized for therapeutic purposes beyond refractive surgery.
  • A two-year clinical experience with excimer laser therapy for corneal surface pathologies is presented.

Purpose:

  • To evaluate the efficacy of phototherapeutic keratectomy (PTK) using an excimer laser for various corneal conditions.
  • To assess treatment outcomes for recurrent erosions, persistent epithelial defects, corneal opacities, limbal infiltrates, and pterygium.

Summary:

  • Phototherapeutic keratectomy (PTK) was performed on 27 eyes across 25 patients.
  • Successful treatment rates included 75% for persistent epithelial defects and 92% for recurrent erosions.
  • Significant visual acuity improvement was noted in patients with corneal opacity, particularly those with bullous keratopathy.

Impact:

  • Excimer laser PTK demonstrates high suitability for treating diverse corneal surface pathologies.
  • The therapy provides a valuable option for managing painful conditions such as bullous keratopathy.
  • Positive outcomes suggest broader applicability of excimer laser in ophthalmic therapeutics.
